that is easy for you say, what air does it separate? is it a bit like an auto airvent (just curious)
but what i really wonder is what is the locking nut that is on the pipe from?

That looks like it fell off a fitting as its a compression nut off something.
I,m starting to have serious doubts about the safety of your system, like has someone removed the header tank and not fitted a Red expansion vessel with safety relief valve etc.
I think you should trace as much as possible and post back here quick.

Right that confirms it, when filled the water will flood out that pipe thats now open.
The system has been converted to a sealed system, there must be an expansion vessel and safety relief valve or the system is dangerous.
Lets start again.
The pipe you took the valve off is/was the cold feed to the boiler, the pipe next to it is/was the expansion pipe.
Where they go or do is important, so where does the cold feed go and where does the expansion pipe go.
Are you saying it connects to the mains cold water or to the main starage tank

the pipe with the valve that I took out that goes to the air seperator comes from the main 50 gallon cold water storage tank. It comes from that and goes directly to the air seperator and no where else.
The other pipe on the air seperator just goes above the main 50 gallon cold water storage tank an presumably is a return. It goes no where else.
only the pipe right at the bottom of the pic labled feed for boiler goes to the boiler
Re-labled diag:
1. comes from the center of the main cold water 50 gallon header tank to the air seperator
2. from the air seperator to the top of the main cold water 50 gallon header tank (return)
3. Feed for the boiler, can't find where it comes from
Are you saying there is ABSOLUTELY DEFINITELY NO small Feed & Expansion tank, in ADDITION to the main cold tank?
If so the whole setup is WRONG, WRONG, WRONG!
Potential effects are pretty catastrophic: contamination of your hot and cold supplies with water from the rads (rust, bacteria and who knows what else), aerated water getting into the rads causing corrosion, airlocks, pump seizure, etc. breach of several parts of the Water Regulations, possible safety hazards from explosion (for a start, if your CH system is venting into the cold tank, where does the vent from the HW cylinder go???)
I think you may have confused a couple of pipes between airing cupboard and roofspace. I do hope so!
